Fixing 401 errors - general Each Web Server manages user authentication in its own way. A security officer (e.g. a Web Master) at the site typically decides which users are allowed to access http://www.checkupdown.com/status/E401.html the URL.

Google to the rescue Why not let millions of Web users tell us themselves what errors they encounter the most? In an indirect way we can do that via Google.
